Nano-mechanical and tribological properties of copper matrix composites reinforced by graphene nanosheets

Nano-mechanical and tribological properties of copper matrix composites reinforced by graphene nanosheets

The impacts of graphene nanosheets content on microstructure, nano-mechanical and tribological properties of the copper matrix composites were investigated. The graphene nanosheets randomly distributed in copper matrix, which obviously hindered its grain growth. The elastic modulus and nano-hardness...
